MC44605

www.DataSheet4U.com MC44605 High Safety, Latched Mode, GreenLinet PWM Controller for (Multi) Synchronized Applications The MC44605 is a high performance current mode controller that is specifically designed for off−line converters. This circuit has several distinguishing features that make it particularly suitable for multisynchronized monitor applications. The MC44605 synchronization arrangement enables operation from 16 kHz up to 130 kHz. This product was optimized to operate with universal mains voltage, i.e., from 80 V to 280 V, and its high current totem pole output makes it ideally suited for driving a power MOSFET. The MC44605 protections enable a well−controlled and safe power management. Four major faults while detected, activate the analogic counter of a disabling block designed to perform a latched circuit output inhibition.
